A pill camera is a piece of equipment used for a procedure known as capsule endoscopy. It was developed in the late 20th century and was approved for use by the FDA in 2001.
The camera is about 1 inch long and one-half inch in diameter, with rounded edges making it shaped like a drug capsule (although slightly larger). It is comprised of a camera, flash, plastic capsule, and transmitter (at present, usually Bluetooth (TM)). It is small enough to be swallowed.
The pill camera is most often used when a disease of the small intestine is suspected. The upper digestive tract can usually be examined with an endoscope, and for problems with the large intestine, a colonoscopy is preferred. However, neither of those two procedures allow examination of the small intestine. In addition, the pill camera is minimally invasive. However, unlike endoscopy and colonoscopy, a pill camera cannot be used to treat a pathology. Pill camera use Capsule endoscopy. Capsule endoscopy is a way to record images of the digestive tract for use in medicine. The capsule is the size and shape of a pill and contains a tiny camera. After a patient swallows the capsule, it takes pictures of the inside of the gastrointestinal tract. The primary use of capsule endoscopy is to examine areas of the small intestine that cannot be seen by other types of endoscopy such as colonoscopy.
Uses
Capsule endoscopy is used to examine parts of the gastrointestinal tract that cannot be seen with other types of endoscopy. Upper endoscopy, also called EGD, uses a camera attached to a long flexible tube to view the esophagus, the stomach and the beginning of the first part of the small intestine called the duodenum. A colonoscopy, inserted through the rectum, can view the colon and the distal portion of the small intestine, the terminal ileum. These two types of endoscopy cannot visualize the majority of the middle portion of the gastrointestinal tract, the small intestine. Capsule endoscopy is useful when the disease is suspected in the small intestine, and can sometimes diagnose sources of occult bleeding or causes of abdominal pain such as Crohn's disease, or peptic ulcers. Capsule endoscopy can be used to diagnose problems in the small intestine, but unlike EGD or colonoscopy, it cannot treat pathology that may be discovered. Capsule endoscopy transfers the captured images wirelessly to an external receiver worn by the patient using one of the appropriate frequency bands. The collected images are then transferred to a computer for diagnosis, review, and display. A transmitted radio-frequency signal can be used to accurately estimate the location of the capsule and to track it in real time inside the body and gastrointestinal tract.
